Interactions of Soluble Iron with Wheat Bran

摘要

ABSTRACTSoft white and hard red wheat bran were found to contain 98.8 and 99.2 water insoluble iron, respectively. As the concentration of iron added to wheat bran was increased, less of the total added iron was bound. Ascorbic acid was found to inhibit binding of ferrous iron to wheat bran. It was found that boiling for 1 hr in a boiling water bath (BWB) had no effect on the destruction of phytic acid in wheat bran, whereas toasting for 1 hr at 178°C (350°F) and boiling for 1 hr in 1N HC1 had a significant effec
